Video demonstration of the UI becoming blurry after opening an image.
When I open or create an image, the whole GUI of Krita becomes blurry and scaled (see the attached video). Before opening the first image, the GUI looks normal.
This only seems to affect the rendering, the mouse cursor still "hits" the GUI elements at their original positions (also demonstrated in the attached video).
I use Krita 3.2.1 on Windows 10. The same behaviour occurs on the latest nightly that I could find (4360147f).
If somebody can give me some hints on how to debug this, I would be willing to fix this and submit a patch.

This is not a bug in Krita, but in the driver for your intel HD620 chip. See https://communities.intel.com/thread/116003 . Intel has fixed this issue, but manufacturers are just now rolling out the broken driver, instead of the latest one.
We will release a version of Krita with a workaround this week. You can already test the release candidate: https://krita.org/en/item/krita-3-3-0-first-release-candidate/
